Definitions

  • the present invention relates generally to forage harvesters having means for processing crop material including maize kernels, these means, for instance, comprising a compressor roll assembly, operable to crack the maize kernels as well as means for processing kernel-free crops such as alfalfa or grass.
  • a forage harvester is an agricultural machine for comminuting crop material for silage purposes.
  • a harvester is mainly used to harvest grass and maize. With grass-like materials (kernel-free) it is sufficient to slit the crop material, e.g. the stems of the plants are cut to length using a cutter, e.g. a rotating knife drum. When cutting maize the cobs may be slit into smaller size but the majority of the kernels are not broken or cracked. This reduces the nutrient value of the silage crop as the kernels are more-or-less indigestible if not cracked.
  • a cutterhead unit of a forage harvester is used to receive crop material harvested from the field and comminute it into forage which is fed by a blower or accelerator to a temporary container, before being stored and eventually foddered to livestock.
  • a blower or accelerator to a temporary container, before being stored and eventually foddered to livestock.
  • the outer skin of the kernels has to be cracked or cut. This can be done by a set of closely adjacent, co-operating compressor rolls with fluted surfaces, installed in front of the blower or accelerator, as shown for example in EP-A-0 177 995 or EP-A-0 664 077.
  • forage harvesters make use of the crop processor to crack the kernels in order to obtain a higher nutrient value of the chopped material.
  • the chopped material is thrown by the cutterhead into the crop processor, which processes (cracks) the kernels and transfers the material with sufficient speed into a blower or accelerator, which in its turn ejects the crop into a trailer or container.
  • the crop processor is redundant but the rolls may still be worn by the sand/earth in the crop material and damaged by stones therein. It is often removed from the material flow by physically removing it from the machine.
  • the chopped material is thrown immediately by the cutterhead into the blower or accelerator and as such it has to travel over a longer distance without intermediate acceleration. In a number of conditions, especially with light or sticky crops, this can result in poor crop transport from cutterhead to the blower or accelerator due to lack of kinetic energy of the material, causing blockage of the channel between cutterhead and blower or accelerator.
  • DE 196 03 928 proposes to solve this problem with an intermediate impeller. This increases the cost and power consumption of the harvester.
  • the change requires a change of belt drive which prevents the changeover being carried out from the drive cab.
  • DE 32 34 657 suggests to shift a blower-crop processor combination sideways so that the chopped crop material is either first processed in the crop processor and passed sideways to the blower or, alternatively, passed directly to the blower. The sideways movement moves a pulley for driving the combination to one side thus requiring a belt change.
  • a hatch from the blower has to be removed to provide an inlet for the crop material and a further hatch installed to close the opening left in the crop processor. This means the changeover cannot be carried out from the drive cab. Also it is difficult to prevent some crop material from accumulating in the crop processor when it is in the inactive position.
  • a forage harvester for handling crop material including kernels comprising:
  • the power unit may be the prime mover of the harvester or of a tractor which tows the harvester, e.g. a power take-off on the tractor.
  • the first drive connection is provided by a belt drive.
  • the power unit may be a hydraulic pump or an electric power supply.
  • the first drive connection may be a flexible hydraulic feed from a hydraulic pump or a flexible cable from an electric power supply.
  • the drive connection is operable to remain substantially operational as the processing unit is moved from the first to the second position.
  • substantially operational includes minor changes to the drive connection, e.g. re-adjustment of an idler roller but excludes major changes such as changing a belt drive.
  • the crop processor unit comprises a compressor roll assembly including a set of closely adjacent co-operating compressor rolls and the blower unit comprises an axle and a suitable blower rotor attached to the axle.
  • the axis of the compressor rolls and the axle of the blower unit are parallel but the present invention is not limited thereto.
  • the axis of rotation of the processing unit is preferably parallel to the axis of the compressor rolls.
  • the distance from the output of the cutter unit to the input of the crop processor unit in the first position is about the same as the distance from the output of the cutter unit to the input of the blower unit when the crop processor unit is in the second position.
  • the blower unit and the crop processor unit are mounted in a frame such that rotation of this frame between the first and second positions is permitted without the removal or disassembly of any drive component of the processing unit, e.g. removal or changing of belt drives or gears.
  • the crop processor rolls are raised from a low non-crop engaging position to a higher crop engaging position.
  • a guide plate may be positioned to isolate the crop processor unit from the blower unit and/or the duct leading to the blower unit.
  • the forage harvester in accordance with the present invention may be self-propelled or may be towable by a tractor.
  • a forage harvester having a main frame 1 on which are mounted ground engaging traction wheels 2 and steering wheels 3.
  • the forage harvester is shown equipped with a crop collecting apparatus, in the form of a row crop attachment 10, suitable for the harvesting of maize, but which can be replaced with a conventional windrow pick-up device or a conventional cutter bar attachment, depending on the type of crop to be harvested.
  • the row crop attachment 10 comprises an attachment frame 12, which supports a plurality of row crop units 14, operable to harvest maize stalks from the field and to convey the same rearwardly to an auger 16, which in turn delivers the crop material to the bite of feeder means installed in a front unit of the forage harvester.
  • the forage harvester has feeding means which comprise lower feeder means, including a forward lower feed roll 26, and a smooth, rear lower feed roll 27, and upper feeder means, including an upper forward feed roll 20 and an upper rear feed roll 21.
  • the lower feed rolls 26, 27 are rotatably mounted in a lower feeder frame 24 and the upper feed rolls 20, 21 are mounted in an upper feeder frame 18, to which the row crop attachment 10 is attached.
  • the upper and lower feeder means rotate to convey the crop material in-between to a cutterhead 36, which comprises a plurality of knives 37, generating a cylindrical peripheral shape or profile, when the cutterhead 36 is rotated.
  • a crop processor roll assembly 41 comprising a set of counterrotating compressor rolls 57 mounted therein, which rolls crack the kernels which are left in the chopped material.
  • the compressor rolls 57 may have a substantially cylindrical, fluted surface.
  • the crop processor roll assembly 41 and a blower rotor 51 are movable as a functional unit between a first position and a second position as will be described later. In a first position the cutter head 36 projects the cut material into the bite of the crop processor roll assembly 41. This delivers the crushed maize kernels to the blower rotor 51 which is installed within a blower housing 48.
  • the blower rotor 51 comprises a plurality of paddles 50, which throw the material upwardly through the blower or accelerator outlet into a discharge spout 52, which can be positioned by an operator to direct the cut crop material as required, normally into a wagon which is moving alongside or behind the forage harvester.
  • the crop processor roll assembly 41 is moved out of the path of the comminuted crop stream and replaced with the blower rotor 51 so that the comminuted material from the cutterhead 36 is thrown directly into the blower rotor 51 (described below) and from there into the discharge spout.
  • the present invention comprises a forage harvester where the blower 51 and crop processor assembly 41 are assembled into one functional processing unit, e.g. are all attached to a frame 53 that pivots around a pair of mutually opposed stub shafts 58 which are journalled in the main frame 1.
  • the frame 53 is represented schematically in Figures 2 and 3.
  • the space between the stub shafts 58 allows passage of the crop material.
  • the blower and crop processor are positioned as in Figure 2.
  • the whole accelerator/crop processor assembly is pivoted around the stub shafts 58 until it reaches the position as indicated in Figure 3.
  • Frame 53 also contains two guide plates 55 and 56, which automatically close the transport channel between the cutterhead and the blower in both positions.
  • Frame 53 is rotatably journalled to the main frame 1 by means of stub shafts 58.
  • the frame 53 may be moved by a suitable actuator, e.g. a hydraulic cylinder (not shown).
  • the frame 53 comprises a pair of struts 90 arranged on both sides of the blower housing 48 and connected to the pivot shafts 58.
  • the upper ends of the struts 90 are interconnected by a transverse beam 91.
  • the blower axle 79 is supported in a pair of bearing blocks fixed, e.g. bolted or welded, to the front faces of the struts 90.
  • the transverse beam 91 provides the necessary structural rigidity to the frame 53.
  • This frame 53 further comprises a second transverse beam 94 interconnecting the struts 90 below stub shafts 58 and a pair of downwardly extending struts 92 which are connected to the struts 90 adjacent stub shafts 58.
  • the processor rolls 57 are journalled in a pair of bearing plates 93 which are connected to the upward and downward struts 90, 92.
  • the plates are arranged on both sides of the blower housing 48 and may also carry the journals of an idler roller 64.
  • the bearing plates are removably connected, e.g. by bolts, to the struts 90, 92.
  • the frame 53 is constituted by the struts 90, 92, the transverse beams 91, 94 and the bearing plates 93.
  • the crop processor rolls 57 and the blower 51 may be driven by a common belt drive which is driven by a drive unit 78.
  • the crop processor rolls and the blower may be driven via a pulley mounted on an axle which coaxial with or near the stub shafts 58 of the frame 53.
  • the length of the common drive belt then remains substantially constant during movement of the frame. There is no substantial length change so that displacements are small enough to be absorbed by small movements of an idler roller such as 63.
  • the idler roller may be spring-loaded so that the accommodating displacement thereof is automatic or the idler roller may be adjusted by hand. Hence, there is no requirement for changing of belts or gears or for demounting the processor rolls 57 when changing the position of the blower and the crop processor.
  • the outer housing 48 of the blower 51 and the crop processor rolls 57 is attached to the main frame 1 and provides sufficient internal space to accommodate the movement of the blower 51 in both operating positions.
  • FIG. 4 A suitable belt drive is shown in Figures 4 to 8.
  • Figures 4 and 6 show the crop processor in the engaged position (similar to Figure 2).
  • Figures 6 and 7 show certain components required to tension a belt drive 60 in more detail, whereas Figures 4 and 5 show the general mechanical arrangement.
  • the main belt drive 60 is driven by a pulley 68 secured to the axle of the main drive unit 78 of the forage harvester.
  • the belt 60 runs over a pulley 61 attached to the axle 79 of the blower 51 for driving the blower 51 and over pulley 80 which is attached to the central axis of the cutterhead 36 for driving the latter.
  • a spring loaded idler roller 63 keeps the belt 60 under tension.
  • a secondary belt drive 66 drives the functional unit of the crop processor rolls 57 and the blower 51.
  • the secondary belt 66 runs over pulley 62 attached to the central axle 79 of the blower 51. Belt 66 is driven by the blower 51. Belt 66 also runs over drive pulleys 67, 69 on crop processor rolls 57. A pulley 69 on one of the rolls 57 is driven by the inner surface of belt 66 whereas the pulley 67 on the other processor roll 57 is driven by the outer surface of the belt 66 in order produce counter-rotation of the two processor rolls 57.
  • Belt 66 is tensioned by a spring loaded idler roller 65 and kept in engagement with pulley 67 by the stationary idler roller 64. As shown best in Figure 6, idler roller 65 is forced downwardly by compression spring 96 via a triangular load member 97.
  • the load member 97 is pivotally attached at its front corner to a transverse beam 98 of the main frame 1 and a pull rod 99 links its lower corner to the strut 90 of the pivotable frame 53.
  • a pull rod 99 links its lower corner to the strut 90 of the pivotable frame 53.
  • the pulley system 62, 64, 67, 69 moves en bloc as the frame 53 is rotated about the pivot shafts 58 to bring the crop processor rolls 57 out of the crop path.
  • spring loaded pulley 63 moves downwards to take up the slack caused by the change of position of pulley 61. Because of the simultaneous movement of the load member 97, the distance between the connection points of the compression spring 96 is maintained such that the force of the idler roller on the belt drive 60 does not vary, notwithstanding the displacement of the blower pulley 61.
  • the drive capacity of the belt drive 60 (determined to an extent by the tension in the belt 60) is not influenced by the position of the crop processor and blower unit.
  • FIG. 8 shows a schematic top view of the drive system with details of frames etc. removed for clarity purposes.
  • a main belt drive 60 is provided which provides the main power to the cutterhead 36 and the blower rotor 51.
  • This belt drive 60 is tensioned by an idler roller 63.
  • a drive sub-system is provided for driving the crop processor rolls 57 from the axle 79 of the blower rotor 51.
  • This may also be a belt drive 66 which is tensioned by the idler roller 65.
  • the crop processor rolls 57 and the blower rotor 51 are interchangeable in the crop flow as one operational processing unit while maintaining the primary drive 60 and the sub-system drive 66 operational during the change.
  • the dimensions of pulleys 80, 67, 69, 62 and 61 are chosen so that there is always enough capacity at any stage in the crop processing to transport the crop to the next stage.
